Recent changes on ar71xx (switch to 4.14, memory compaction, ...) cause
an increase in kernel size, making it too big for some devices.
Move these devices to the tiny target, where kernel symbols and
optimization for speed are disabled, reducing the kernel size.
Devices:
- EnGenius ENS202EXT
- OCEDO Koala
Compile-tested targets:
- ar71xx->generic->default
- ar71xx->smallFlash->Default

F9K1115v2 has a kernel partition size of 1408 kB.
Since kernel 4.9.x+ the kernel image for this device compiled had exceeded
the kernel partition size limit and thus failing size check.
The kernel image generated for this device
under ar71xx tiny target is 1329.67 kB < 1408 kB.

Move boards to the tiny subtarget which break the build if the kernel is
set to "Optimize for performance".

This new subtarget sets the small_flash flag and removes unused kernel
configuration.
small_flash removes KERNEL_KALLSYMS, which saves ~107KB in the default
configuration; removing unneeded hardware support from ar71xx/tiny saves
another ~18KB (both after LZMA).
